Brass Nautical Antique Compass 2 To 6 Inches In Diameter

Brass Nautical Antique Compass is crafted from solid brass with an antique or vintage finish, often featuring a naturally aged patina or hand-polished surface. It includes a floating or dry card dial marked with cardinal directions and a 360-degree scale for navigation accuracy. The needle is magnetized and enclosed under a convex or flat glass cover. Typically housed in a brass case or a handcrafted wooden box, the compass ranges in size from 2 to 6 inches in diameter and weighs between 200 grams to 1 kilogram. It may feature a gimbal mount for stability at sea or be designed as a handheld or tabletop unit. Originating from 18th to early 20th-century nautical use, it serves as a functional navigational tool, a collectible piece, or a vintage maritime décor item. Calibration is manual, using Earth’s magnetic field for orientation.
